I did that with a 5 gallon bucket. Deer and turkey would literally come running (in the winter time).
No doubt in my mind that we can condition deer to just about anything. The sound of a chainsaw is a dinner bell. They pay no attention to my tractor. I can handle trail cams near my home (where deer are used to smelling me) with bare hands. I can walk into my plots wearing crocs and deer pay no attention to my ground scent...even 15 minutes later. I know that to be true because I watch it happen from my home all the time.
We also condition deer to look up into trees. Sloppy stand set-ups with no back cover, or careless movement while deer are present have conditioned deer to look up as much as they look anywhere else. Which makes me wonder...If deer are looking up so much, have they also been conditioned to recognize what a "stand" is, and if so, will some (mature) deer avoid the area?
We condition deer when, all of a sudden, 2 weeks before bow season, there are humans walking in places where they haven't walked since the end of the last hunting season.
Yeah, we condition and educate deer all the time. Now, would the OP's thought of adding a scent or oil condition them to come to us thinking there is food? As long as our human odor mixes with the other oil/scent, I doubt many deer will fall for it under hunting or daylight conditions. Same with cover scents. If you think deer cannot sort-out thousands of odors all at the same time, then you don't truly understand how amazing their olfactory system is.
